ABSTRACT Abrasive water jet machining is classified as a non-conventional machining process. Abrasive water jet machining uses water jet under high pressure as a tool, with added particles of abrasives. The most significant characteristic of the abrasive water jet cutting technology is cold cutting, which does not have a thermal effect on the material. The objective of the experimental investigation is to conduct research of the machining parameters' impact on surface roughness of the machined parts, and derive conclusions referring to the manner in which certain machining parameters affect surface roughness. Experimental investigation was conducted in the way that samples of two different materials were cut on the machine using different machining parameters. Measurement of different surface roughness parameters has been conducted after the cutting.

Introduction
In the battle to reduce costs, engineering and manufacturing departments are constantly on the lookout for an edge. The water jet process provides many unique capabilities and advantages that can prove very effective in the cost battle. Learning more about the water jet technology will give us an opportunity to put these cost-cutting capabilities to work. Beyond cost cutting, the water jet process is recognized as the most versatile and fastest growing process in the world. Waterjets are used in high production applications across the globe. They compliment other technologies such as milling, laser, EDM, plasma and routers. No poisonous gases or liquids are used in Waterjet cutting, and Waterjets do not create

    c) The control of cutting-fluid temperature is very important in operations where high dimensional accuracy is essential. As expected, the fluid heats up during its service throughout theday (due to the energy dissipated during machining), its temperature begins to rise. This, inturn, raises the temperature of the workpiece and fixtures, and adversely affects dimensionalaccuracy. Temperature-control units are available for maintaining a constant temperature in cutting-fluid systems.…

    Hampton Machine Tool Company, a machine tool manufacturer, was founded in 1915. Hampton 's customer base is made up primarily of military aircraft manufactures and automobile manufactures in the St. Louis area. Hampton felt the boom in the 1960s with record setting profits in the mid to late 1960s. Hampton slowed down in the 1970s with the withdrawal from Vietnam War and the oil embargo. Hampton stabilized by the late 1970s and now has a larger market share as other competitors were unable to make it through the tough times.…

    In the novel Their Eyes Were Watching God written by Zora Neale Hurston, the protagonist, Janie, and her husband for a respectable portion of her life, Jody Starks, seek courtship for entirely different reasons. Janie pursues sexual and emotional fulfillment as she journeys to the horizon and to a place of limitless possibility, while the male domineering Jody Starks seeks only after power, control, and a good place in society. These dramatic differences in ideals of love are the source of conflict between Janie and Jody and utterly shift Janie’s understanding of freedom and what it means to be free. Their different outlooks also lead to their downfall as a couple, and the downfall of Jody Starks as a man.…

    In his essay, When We Can’t Wait on Truth: The Nature of Rhetoric in the Rhetoric of Science, Nathan Crick explores the question, what is the relationship between rhetoric and truth? Crick’s purpose is to inform all readers that rhetoric has a crucial validating role in science. The author references Alan Gross’s published work, The Rhetoric of Science, in which he contributed to the initiation of a controversy concerning the place of rhetoric in science studies, while also arguing for the continued significance of the classical rhetorical tradition. Gross’s main idea of the text was “rhetorically, the creation of knowledge is a task beginning with self-persuasion and ending with the persuasion of others” (Gross, 1996, 3). However, in…

    Destin Brass produces three products used for water purification systems: valves, pumps and flow controllers. They are seeing high competition in the pumps market while competitors are reducing the prices on pumps. Because they do not have any design advantages to their product, they feel they need to follow the market and lower their prices as well. A meeting was held to discuss the declining profits and a proposal to change their overhead allocation method was proposed.…

    Hampton Tool Machine

    Hampton Machine Tool Company was established in 1915, whose customers were aircraft and automobile manufacturers located in the St. Louis area. The company had a large success rate throughout the 1960’s, with an unfortunate decline throughout the mid 1970’s in sales. The company was able to recover in the years following due to a large increase in military aircraft sales, especially the company’s conservative financial policies. Mr. Benjamin G. Cowins, president of Hampton Machine Tool Company requested an initial loan of $1 million from the St. Louis National Bank in order to purchase the stocks of several dissident shareholders, with a current interest rate of 1.5% monthly. Even though the company had excess money for normal operations, they did not have enough for their stock redemption that the company was currently interested in. However, Mr. Cowins sent Mr. Jerry Eckwood an additional letter requesting for an additional $350,000 to their loan in order to improve the overall performance of the company.…

    In conclusion the hydrodynamic cavitation reactors provide huge potential and convincing approach for various immediate industrial scale implementations as compared to acoustic reactors. Moreover, the feasibility of scale up of this reactor is relatively easier since plenty of research has already been done on fluid dynamics in the downstream of constriction valves. The operating efficiency and energy dissipation also goes down we scale up the reactor.…

    Impact of Jet

    • 649 Words
    • 3 Pages

    2 Theory When a rubber ball strikes a solid surface it nicely rebounds from the solid surface. The amount of rebound would depend on the coefficient of restitution. However, when a steady fluid jet strikes a solid surface, it does not rebound. But, a stream of fluid is formed which moves over the surface and the fluid leaves the surface tangentially. If a fluid jet is impacting a horizontal plate, at an angle θ, the rate of change of momentum can be equated to the force exerted by the jet on the plate. When a vertical fluid jet strikes a horizontally positioned plate, the value of θ will be 90°. A control volume analysis can be performed to give the force F = ρQV, (1) where ρ is the density of the water, Q is the jet flow rate and V is the velocity of the jet. For the case of a hemispherical shell when the stream of water is turned back by 180o, the force experienced by the shell will be F = 2ρQV, (2) two times the force experienced by the flat plate. 3 Experimental Set-up The set up consists of a closed cylindrical container housing the horizontal plate/hemispherical shell to receive the impact of the jet. The vertical water jet is produced by a pump forcing water through a nozzle of diameter 6mm for the flat plate and of diameter 8mm for the hemispherical set up. The flow rate through the nozzle is measured by a rotameter. The velocity of jet could be obtained by knowing the flow rate. 4 Experimental Procedure Switch on the motor and using the two gate valves control the flow rate. Place suitable weights to counter balance the impact force of the liquid jet. When the load is higher than the impact load of the jet, the jet will be blocked by the plate. When the load is low the load arm will rise up and touch the top part of the housing. Adjust the flow rate for any selected weight so…

    There is many factors that contribute to the roughness surface, The designer using certain symbol normally draws the quality and surface texture pattern of a component, which is to be machined. Components like heat transferring tube and brake must have controlled surface texture. For the heat transferring tube, if the surface of the tube is a bit rough, the tube will transfer the heat even faster. The same thing also applies to the brake. Brake needs rough surface to ensure its…
